IMPROVEMENT IN CAR-PUSHERS.

Specification forming part of Letters Patent No. 190,848, dated May 15,1877; application filed April 26,1877.

To all whom it may concern:

Be it known that I, JOSEPH E. GEARHART, of West Decatur, in the countyof Olearfield and State of Pennsylvania, have invented certain new and.useful Improvements in Car- Pusher; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use it, reference being had to the accompanying drawings, whichform part of this specification.

My invention relates to an improvement in car starters and pushers andit consists in the arrangement and combination of parts that will bemore fully described hereinafter, whereby a cheap, simple, and efficientmachine is produced.

The accompanying drawings represent my invention.

a represents an iron frame or base, which has its lower edge cut away,so as to fit on the top of the rail, and which has the two ears 0 formedon its top, to pivot the lever d between. To the rear side of this frameor base is secured the brace e, the rear end of which is curveddownward, so as to rest upon the top of the rail and hold the base inposition. Pivoted in a recess made in the bottom of the base are the twogriping-jaws, which have a suitable spring or springs, z, pressingdownward upon their inner corners, so that the lower outer corners willbe thrown wide apart, and the two lower inner corners y will be made toproject down below the lower edge of the base a. As the base rests uponthe top of the rail,

as soon as power is applied to the lever 01 to push the car forward, thedownward pressure upon the base causes the corners g to be forced upwardinside of the base, and as they rise upward the lower outer corners,with the jaws 0 upon them, are drawn inward together, so as to-clamp theouter edges of the top of the rail, and the greater the pressure uponthe lever the tighter do these jaws gripe.

Secured to the under side of the lever 01 is the spring I, which bearsdown upon the top of the brace e, and keeps the base from tiltingforward, as shown. Secured to the top of the lever is another spring, a,which has its outer end passed through under the shoe in such a manneras to hold the shoe always ready for use, and yet allow it to yieldfreely in any direction desired.

Having thus described my invention, I claim- 1. The combination, in acar-starter, of the base a, brace e, lever d, two griping-jaws, and

spring 6 with the spring 1 and shoe, substantially as specified.

2. The base a, having a recess in its lower part, in combination with'the two gripingjaws and spring i, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this18th day of April, 1877.

JOSEPH EMORY GEARHART.
